JACOB B. BEAM, OF PUNXSUTAWNEY, PENNSYLVANIA.

AUTOMOBILE RADIATOR.

Application filed July 30, 1917.

T 0 all whom it may concern:

Be it known that I, JAooB B. BEAM, a citi zen of the United States,residing at Punxsutawney, in the county of Jeflerson and State ofPennsylvania, have invented certain new and useful Improvements inAutomobile Radiators, of which the following is a specification.

This invention relates to radiators for use in connection with motorvehicles for the purpose of cooling the water which circulates in thecylinders of the engine and is an improvement on Patents #l,0l9,122,#1,026,S95, #1,026,896, granted to me March 5, 1912, and May 21, 1912,respectively.

The primary object of the invention is to provide a radiator casingstamped from sheet metal, in which the casing is utilized for thecirculation of water, the said casing containing upper and lower waterchambers and independent tube sections communicating with said waterchambers to provide a water circulation, the casing also being providedwith a front finishing bead, obviating the necessity of adding anadditional finishing casing,"thereby simplifying and improving theconstruction of the radiator and reducing the cost of maintenance.

Another object of the invention is to pro- I vide means whereby theindependent tube sections may be inserted or removed from the rear ofthe caslng, the radiator being susceptible of use with one or more ofthe independenttube sections removed, provision being made for closingthe opening by which the water chambers establish communication with thetube sections.

' The invention further consists of a novel manner of forming andassembling the different parts of the radiator casing to provide waterchambers therein and to provide for the convenient connection of theheaders of the independent tube sections, some of these headers beinginserted and connected from the rear of the casing, while in one form ofthe invention the headers are secured in position by the assembling ofthe lower water chamber with the remainder of the casing.

With the above and other objects in view, the invention consists of thefollowing novel combination and arrangement of parts, hereinafter morefully described and illustrated in'the accompanying drawings, in whichFigure 1 is a sectional elevation of one Specification of LettersPatent.

Figure 17 is an enlarged sectional View on the line 17 17 of Figure 1.

In the usual construction of radiators, the radiator proper isordinarily made of a single casting, which contains the upper and lowerwater headers or chambers connected together by the water circulatingtubes. In this form of radiator it is necessary to make the casting ofconsiderable thickness in orufacture and increasing the amount oi?material necessary to construct a radiator.

In order to overcome these and other disadvantages, the presentinvention contemplates the provision of a casing stamped from sheetmetal, in which there is termed upper and lower water chambers,connected together by independent tube sections or units the novelmanner of forming the casing, simplifying its construction andmaterially reducing the cost of nianutacture. As shown in theaccompanying drawings, reference being had to Figures 1 and 2, there isprovided a casing in which the front 10, sides 11, top 12 and bottom 13are stamped froma single piece of sheet metal and shaped to provide afinishing" bead 13 around the opening M, which 15 provided with watercirculating tubes.

Formed in the upper part of the casing is a water chamber 146, thischamber being formed by inserting within the upper end of the casingjust described a sheet metal plate 15, illustrated in Figure 13. Thisplate is shaped to provide a rear wall 16 of the casing and a bottomwall 17, the latter being inclined as shown to permit of the readyinsertion and removal of the independent tube sections to be laterdescribed. The plate 15 is brazed or otherwise secured within thecasingand forms an absolutely water tight chamber. The plate 15 isformed with an inset portion 18. the vertical wall 19 of which isprovided with a plurality of spaced openings 20, these ()Qllllig'fibeing formed with a concentrically arranged seat 21, which is shown inFigure 6 oi the drawings.

The casing lower water chanib r 22, which is formed by plate 23, stampedfrom sheet metah this plate being also provided with an inclined upperwall 2 llor a purpose hereinafter apparent. Thercarwall of the casing 23is provided with a plurality of spaced openings 25, which are arrangedin vertical align ment with the openings 20 and like these lat ,teropenings are termed with concentrically arranged seats 26, thisconstruction being best-illustrated in Figure 17.

The upper water chamber is provided with a water inlet 27, and the lowerchamber with an outlet 28, for connection with the ordinary watercirculating SYStGIIIOf an'engine. Communication is established betweenthe upper and lower water chambers through tlienicdium of water tubes29, which are sinillar in construction to the tubes shown is furtherprovided with a and described in the above mentioned patents. Thesetubes are arranged in independent tube sections, each of which isprovided with an upper water header 30 and'a lower water header 81, theformer being best illustrated in Figure 6 ot the, drawings. 'f fhisupper water header is stamped from sheet metal and is provided with anopen bottom, beneath unich is s cured a plate 32. This plate is formedupon each of its side edges with a flange which is adapted to be engagedwith the side and end walls of the header The plate is further providedwith inwardly projecting spaced fin- ?i-l. which provide notches 35, thelatter being ada iteitl to receive the upper ends of the tubes 29. itsin my former patents, these tubes are provided with. transverselyarranged horizontal projections or bosses 36 the "topmost boss acting asa stop to limit the entrance of the upper portion of the tubes 29 intothe j jilPrtQ. The headers 31 are provided with plates 37. which aresimilar in construction to the plates 82 and are adapted to close theupper ends of the said headers. The lower ends or" the tubes 29 areinserted in the notches formed between the fingers of the pl ates 37.the lowermost boss of the'tubes :ctii g as astop after the manner of theupier boss previously mentioned. 7

lVhen these headers and tubes have'been as inbled. they are dipped so asto securely hold the partstogether. the transverse bosses of the tubesabutting and effectually closing the opening in. the plates 32 and 37.,so that in absolutely wager tight joint is obtained.

Both'the uppci andlower headers are formed with spared openings 38 and39 revel are arranged out- 7 1 4.0 and ll, these flanges i ..th insetportions torini ioulders 4:2 and 43, between which and toe seatsprovided around the openings in the upp and lower water chambers arepositionei'l. kets t l. These gaskets are L-shaped inpress-sectionand"form a double a the points indicated by the reference nuine s 4:) and46. so that an interlocking joint provided between the water chambersand headers and any liability of leak age thereby prevented.

ln the assembling of the parts just descrilicd. the independent tubesections are positioned so that their projecting flanges will ntend,within the seats on the upper and lower water cl ainbers and theindependent tube sections are held in this position b means of screws 47adapted to engage threaded openings 48 in the lower water chamber andsimilar openings 49 in' the upper water chamber these screws carryingspanners 50, which bridge the space and engage the adjacent edges ottheheaders.

I In ordejr to secure the radiator in position upon a. vehicle,there-are provided ataround which taching lugs 01, each of which isstamped "from a sing e piece of metal and folded to l I i provioe ila52, having regis er-im openings F3 The nd of the pl 9 ied is bent o toprovide ii nay be crazed or otherwise cured to the a. Q There is furtherprovided upon this attaching lug an integral trout wall 55, one end ofwhich is curved shown at 56 to conform to the bottom edge of theradiator casing.

[he construction shown in Figures 3 and 4- 0f the drawings is similar inall respects to it just described, except that the front 5'? the casingis formed in an outw; rdly projecting point or V-shapedatter the mannerof radiators employed on some types of motor vehicles. To accomplishthis, it is necessary to extend the inset portion 8 a greater distance,and as the vertical wall oi this portion is arranged at an angle asshown at 58 in Figures 4 and 10, the seats which surround the openings60 are arranged an angle therein. This is done in order that theindependent tube sections may be positioned in the same manner as thesections in the form just described.

In the form shown in Figures 4: and 10, the flanges 61 which surroundthe openings 62 of the water headers 63 01" the independent tubesections are so disposed as to permit of the engagement of the flangeswithin the seats 59. The screws 64, by means of which the headers areheld in engagement "ith the water headers are received within threadedopenings 65, these openings being disposed in alignment with the seatsand flanges 59 and 61.

in the form of the invention shown in gures 11 and 12, the casing isformed by s amping the front wall 66, the top wall 67 and side wall 68from a single piece of sheet metal. the upper water chamber 69 beingformed by securing the plate 70 stamped in a suitable form and securedafter the manner of the plate 15, to provide the rear and bottom wallsforthe chamber 69.

The lower water chamber has its front wall 1 formed separately from theupper water chamber, in this respect differing from the constructionillustrated in Figures 1 and e 2. This lower water chamber 72 is formedwater headers H, the difference being that the openings by whichcommunication is established between the upper and lower water chambers,are formed in the bottom and top walls of the water chambers and thelower water chamber and engaging the block 80 brazed to each of the sidewalls of the casing, this last mentioned block being; formed with anoffset 81 to provide attaching flanges for the radiator.

As will be seen from the foregoing description and the accompanyingdrawings, each of the independent tube sections is re movable and theradiator may be used after the removal oi one or more of these sections,the openings provided in the water chambers being closed by means of ablock, in the form of a gasket 82, which is positioned upon the shank ofa T-bolt 83. Also positioned upon the shank of the bolt is a disk 8% anda clamping nut 85. By reference to Figure 17 it will be seen that thebolt 83 may have its head inserted through any one of the openings inthe water chambers and the gasket 82 positioned against the flange, thegasket being securely held in such position by adjusting the nut 85.

It is believed that from the foregoing description when taken inconnection with the accompanying drawings, the construction andadvantages of the invention will be apparent. The right is reserved tomake such changes in the form and proportion thereof as will fall withinthe scope of the claims hereto appended.

Having described the invention, what is claimed is:

1. A radiator for motor vehicles embodying a casin stamped from sheetmetal and formed to provide three walls of both an upper and a lowerwater chamber, sheet metal plates stamped to form the remaining wall. ofeach of said chambers, seats Formed in said plates, said seats includinginwardly extending tubular members and inwardly extendingannular flangessurrounding the inner ends of said members, independent tube sectionsconnecting said water chambers, said sections each being provided with aheader having a flanged opening therein adapted to be positioned withinone of the seats of the water chamber, an inwardly ofi'set restrictedextension provided around the flanged openings of the headers and spacedfrom the plate flanges to provide gasket spaces, a gasket positionedwithin each of said spaces and means for connect- Cir position.
